Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Kitchener. Most all of them frequently require skilled AC repair.

Making sure the air filter isn’t dusty and airflow isn’t lowered are the only tasks you can safely fix on your own. If you need to put in a new the filter, you can accelerate the defrosting process by turning off the system and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice is gone, move the temperature back to normal. If your unit freezes a second time, call Boehmers/Cronin Emery Service Experts to repair the issue.

Here are several other reasons why your equipment may be freezing up.

Insufficient refrigerant—Freezing up can be caused by a refrigerant leak.

What creates a leak?

  • Weakened solder joints
  • Friction from piping jarring against an object
  • Cracked valves
  • Slack fittings

How long your equipment has been working and the area of the leak play a part in whether you should repair or replace your AC system.

Dirty evaporator coil—Over time, the evaporator coil becomes dirty and leads to issues much like a clogged filter. You’ll slowly receive lower airflow until your system freezes or halts cooling. You’ll need to call Boehmers/Cronin Emery Service Experts to fix the issue.

Defective blower motor or relay—A blower motor going at an inaccurate speed or not working at all can lead to freezing. It might also be sporadic, going at full speed and slowing down after it heats up. Or a relay may make it run one time and not the following time. In either situation, you will need to contact Boehmers/Cronin Emery Service Experts to correct the trouble.

Requesting regular AC maintenance or heat pump maintenance can help you bypass this malfunction. Our pros will comprehensively examine and clean your system, which often allows us to find minor issues before they turn into major problems.
